A planet where it shouldn't be: in the 'hot Neptune desert', astronomers found a world with an atmosphere of carbon monoxide and carbon dioxide. Heavy molecules, like thick jelly, keep it from evaporating under the star's rays.
🎯 The dayside of LTT-9779 b is baked to 2000°C — that's as hot as an electric stove's coil glowing red-hot.
C/O \approx 1
The ratio of carbon to oxygen in the atmosphere is roughly one.
